Command Groups

transcribe — Speech to subtitles

transcribe <input> [--asr bijian|jianying|whisper-api|whisper-cpp] [--language CODE] [--format srt|ass|txt|json] [-o PATH]
  • bijian (default): Free, Chinese & English, no setup
  • whisper-api: All languages, requires --whisper-api-key

subtitle — Optimize and translate

subtitle <input.srt> [--translator llm|bing|google] [--target-language CODE] [--layout target-above|source-above|target-only|source-only] [--no-optimize] [--no-translate] [-o PATH]
  • Three steps: Split → Optimize → Translate
  • Bing/Google translators are free
  • 38 target languages supported (BCP 47 codes)

synthesize — Burn subtitles into video

synthesize <video> -s <subtitle> [--subtitle-mode soft|hard] [--quality ultra|high|medium|low] [-o PATH] [--review-script PATH] [--max-script-diff-ratio FLOAT]
  • Mirrors the stable backend synthesize surface
  • Subtitle look is controlled by the subtitle asset/backend version, not extra harness flags
  • --review-script checks subtitle/script drift before the final export
  • Lower --max-script-diff-ratio when copy accuracy matters more than resilience

process — Full pipeline

process <input> [--asr ...] [--translator ...] [--target-language ...] [--subtitle-mode ...] [--layout ...] [--no-optimize] [--no-translate] [--no-synthesize] [-o PATH]

review — Consistency check and preview

review <input.srt|input.ass> [--script PATH] [--max-diff-ratio FLOAT] [--preview-video PATH] [--preview-at TC] [--preview-output PATH]
  • Detects subtitle/script drift before a hard-burn
  • Can render a single review frame instead of producing a full final video

styles — List style presets

styles
  • Reports whether the installed backend exposes preset styling support

config — Manage settings

config show
config set <key> <value>

download — Download online video

download <URL> [-o DIR]

JSON Output

All commands support --json for machine-readable output:

cli-anything-videocaptioner --json transcribe video.mp4 --asr bijian
# {"output_path": "/path/to/output.srt"}

Backend Notes

  • The upstream backend currently requires Python >=3.10,<3.13; prefer Python 3.12 for matrix runs.
  • Advanced synthesize-time style flags are backend-version dependent. Use styles to check whether the installed backend exposes them.
  • Compatibility flags such as layout, render_mode, style, style_override, and font_file should be treated as non-stable unless styles and the installed backend confirm they are supported.
